Create a watercolor portrait of a fiery mage with vibrant, glowing flames around him. Use impasto techniques to enhance the texture and intensity of the fire, making it seem almost three-dimensional and dynamic. Capture the mage's determined expression and flowing robes, emphasizing the interplay between his fiery aura and the serene background. The overall aesthetic should evoke a sense of power and mysticism, with rich, saturated colors and a blend of soft and sharp edges to highlight both the mage and the fiery elements.
